During Christmas Week, residents near the New Orleans lakefront experienced a rare meteorological phenomenon known as a fogbow. This optical display, resembling a “white rainbow,” captivated those enjoying the holiday strolls along the waterfront. The fogbow appeared as a ghostly white arc in the sky, providing a unique festive spectacle for onlookers.
Understanding the Fogbow
A fogbow forms under specific conditions when both fog and sunshine are present simultaneously. Unlike a traditional rainbow, which is created by larger raindrops refracting sunlight, a fogbow is produced by much smaller water droplets found in fog. When sunlight passes through these tiny droplets, the colors typically seen in a rainbow blur together. As a result, the fogbow takes on a softer, ethereal appearance.
This phenomenon occurs opposite the sun, meaning that to spot a fogbow, observers should have the sun at their back. The optical effect can be difficult to capture, making it a delightful surprise for those fortunate enough to witness it during their holiday festivities.
A Christmas Surprise for Local Residents
As families and individuals strolled along the lakefront, the fogbow provided a picturesque backdrop to their Christmas celebrations. This rare occurrence brought joy and a sense of wonder to the community, emphasizing the beauty of nature even during the colder months.
Residents are encouraged to share their experiences and photographs of the fogbow phenomenon. Those who captured this fleeting moment can email their images to [email protected] or text them to 504-529-4444.
